[0002] Sleep is an essential physiological activity for humans. It accounts for nearly one-third of a person's life, and sleep quality is closely linked to human health. Good sleep replenishes the body's essential faculties, enhances immunity, and promotes normal growth and development. However, with the acceleration of urbanization and modernization, people are experiencing increasing stress, and sleep quality is gradually declining.

[0003] In order to solve the aforementioned technical problems, the prior art publication number is CN 109044016B, which provides a healthy sleep pillow and an adjustment method thereof.
